The UK has officially left the European Union after 47 years of membership - and more than three years after it voted to do so in a referendum.
The historic moment was marked by both celebrations and anti-Brexit protests.
Candlelit vigils were held in Scotland, which voted to stay in the EU, while Brexiteers partied in London's Parliament Square.
Prime Minister Boris Johnson has vowed to bring the country together and "take us forward".
